pub struct ConsumerGroupMetadata {
pub group_id: String,
pub generation_id: i32,
pub member_id: String,
pub group_instance_id: Option<String>,
}Expand description
The identity that a consumer presents to a transactional producer for KIP-447 offset-commit fencing.
This mirrors the JVM’s
org.apache.kafka.clients.consumer.ConsumerGroupMetadata.
Fields§
§group_id: StringThe consumer group id.
generation_id: i32Classic-group generation id, or the member epoch for a KIP-848 next-gen
group. The client sends it verbatim in
TxnOffsetCommitRequest.generation_id, which matches the JVM wire
convention. The coordinator interprets it per group kind.
member_id: StringThe member id that the coordinator assigned at join time. It is empty for a simple consumer, which uses manual assignment and has no group membership.
group_instance_id: Option<String>group.instance.id for a static member. None for a dynamic member.
Implementations§
Source§impl ConsumerGroupMetadata
impl ConsumerGroupMetadata
Sourcepub fn for_group(group_id: impl Into<String>) -> ConsumerGroupMetadata
pub fn for_group(group_id: impl Into<String>) -> ConsumerGroupMetadata
Metadata for a producer that commits offsets to a group it is not a member of, that is a manual partition assignment or a simple consumer.
The group coordinator applies no generation or member fencing to this shape.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();§fn on_primary(&self) -> Painted<&T>

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
