Struct Segment

Source
pub struct Segment {
    pub key: String,
    pub included: Vec<String>,
    pub excluded: Vec<String>,
    pub unbounded: bool,
    pub version: u64,
    /* private fields */
}
Expand description

Segment describes a group of contexts based on keys and/or matching rules.

Fields§

§key: String

The unique key of the segment.

§included: Vec<String>

A list of context keys that are always matched by this segment.

§excluded: Vec<String>

A list of context keys that are never matched by this segment, unless the key is also in included.

§unbounded: bool

Unbounded is true if this is a segment whose included list is stored separately and is not limited in size. Currently, the server-side Rust SDK cannot access the context list for this kind of segment; it only works when flags are being evaluated within the LaunchDarkly service.

The name is historical: “unbounded segments” was an earlier name for the product feature that is currently known as “big segments”. If unbounded is true, this is a big segment.

§version: u64

An integer that is incremented by LaunchDarkly every time the configuration of the segment is changed.

Implementations§

Source§

impl Segment

Source

pub fn unbounded_segment_id(&self) -> String

Retrieve the id representing this big segment.

This id will either be the segment key if the segment isn’t a big segment, or it will be a combination of the segment key and the segment generation id.
