Struct EmbeddingUsage 

#[non_exhaustive]
pub struct EmbeddingUsage {
    pub input_tokens: u32,
}

Token-accounting metadata an Embedder reports alongside the computed vector. Mirrors the ChatModel Usage shape so cost meters can charge embedding calls with the same machinery they use for completions.

Marked #[non_exhaustive] so future fields (cached_tokens, total for cost, latency_ms) are forward-compatible.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

input_tokens: u32

Tokens the embedder counted as input. 0 when the backend does not surface a count (some local impls do not).

Implementations

impl EmbeddingUsage

pub const fn new(input_tokens: u32) -> Self

Build a usage record with the supplied input-token count.

Trait Implementations

impl Clone for EmbeddingUsage

fn clone(&self) -> EmbeddingUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmbeddingUsage

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

Formats the value using the given formatter.

impl Default for EmbeddingUsage

fn default() -> EmbeddingUsage

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EmbeddingUsage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EmbeddingUsage

fn eq(&self, other: &EmbeddingUsage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for EmbeddingUsage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for EmbeddingUsage
