Struct Segment

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

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

impl Segment

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.

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Segment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Segment

fn default() -> Segment

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Segment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Segment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Versioned for Segment

fn version(&self) -> u64

Retrieve the version for this item instance.

fn is_greater_than_or_equal(&self, version: u64) -> bool

Determine if this item’s version is greater than or equal to the provided version parameter.
