Struct ModalityTokens 

pub struct ModalityTokens {
    pub modality: String,
    pub tokens: u32,
}

Token count for a specific modality.

Used in per-modality breakdowns like UsageMetadata::input_tokens_by_modality.

Example

if let Some(breakdown) = &usage.input_tokens_by_modality {
    for modality_tokens in breakdown {
        println!("{}: {} tokens", modality_tokens.modality, modality_tokens.tokens);
    }
}

Fields

modality: String

The modality type (e.g., “text”, “image”, “audio”).

Uses string for forward compatibility with new modalities per Evergreen principles.

tokens: u32

Token count for this modality.

Uses u32 since token counts are never negative. If the API returns a negative value (which would be a bug), it’s clamped to 0 with a warning log.

Trait Implementations

impl Clone for ModalityTokens

fn clone(&self) -> ModalityTokens

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModalityTokens

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ModalityTokens

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ModalityTokens

fn eq(&self, other: &ModalityTokens) -> 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 ModalityTokens

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
