Struct FastIdGenerator 

pub struct FastIdGenerator { /* private fields */ }

An IdGenerator implementation optimized for lightweight, locally-scoped identifiers.

This generator produces short, incrementing identifiers that are Base64-encoded. This makes it well-suited for cases such as StreamId generation, where:

• IDs only need to be unique within a single process or session
• Predictability is acceptable
• Shorter, more human-readable identifiers are desirable

Implementations

impl FastIdGenerator

pub fn new(prefix: Option<&'static str>) -> Self

Creates a new ID generator with an optional prefix.

Arguments

• prefix - A static string to prepend to IDs (e.g., “sid_”).

Trait Implementations

impl<T> IdGenerator<T> for FastIdGenerator

where T: From<String>,

fn generate(&self) -> T

Generates a new session ID as a short Base64-encoded string.

Increments an internal counter atomically and encodes it in Base64 URL-safe format. The resulting ID is prefixed (if provided) and typically 8–12 characters long.

Returns

• SessionId - A short, unique session ID (e.g., “sid_BBBB” or “BBBB”).
