Struct Speculation 

pub struct Speculation<'a> {
    pub draft_tokens: &'a [TokenId],
    pub draft_logits: &'a [Vec<f32>],
    pub target_logits: &'a [Vec<f32>],
    pub temperature: f32,
}

Input to verify_speculation: logit vectors at each speculation position.

For a speculation of N draft tokens:

• draft_logits.len() == N — the distribution the draft model used to sample each draft token (aligned with draft_tokens).
• target_logits.len() == N + 1 — the target model’s distributions at each position; the extra slot is the bonus-token draw after all drafts are accepted.
• draft_tokens.len() == N.

Fields

draft_tokens: &'a [TokenId]

draft_logits: &'a [Vec<f32>]

target_logits: &'a [Vec<f32>]
