Struct Logprob 

pub struct Logprob {
    pub logprob: f64,
    pub rank: Option<u32>,
    pub decoded_token: Option<String>,
}

vLLM’s log probability of one token at one position, as reported in the prompt_logprobs response field.

OpenAI’s logprob objects carry token / logprob / bytes / top_logprobs; vLLM’s prompt logprobs instead key each position’s map by token ID and report the vocabulary rank plus the decoded text.

Fields

logprob: f64

The log probability of this token.

rank: Option<u32>

This token’s rank in the vocabulary at this position, starting at 1. Omitted when the server did not compute it.

decoded_token: Option<String>

The decoded text of this token.
