Struct TokenBlockMmInfo 

pub struct TokenBlockMmInfo {
    pub mm_hash: u64,
    pub offset: usize,
    pub length: usize,
}

Metadata describing a single multimodal placeholder run within a token sequence.

A run occupies length consecutive slots starting at offset. The token IDs at those slot positions are opaque for hashing — the (mm_hash, run_offset) pair drives the per-slot bytes during block formation.

See compute_block_bytes_with_mm for the byte-encoding rule.

Fields

mm_hash: u64

Hash identifying the multimodal object (image / audio / etc.).

offset: usize

Start position of the placeholder run in the full token sequence (zero-based).

length: usize

Number of placeholder slots in the run.

Implementations

impl TokenBlockMmInfo

pub fn checked_end(&self) -> Option<usize>

Returns the exclusive end position of this run, or None on usize overflow.

pub fn end(&self) -> usize

Returns the exclusive end position of this run.

Panics

Panics if offset + length overflows usize. Prefer Self::checked_end in validation paths; this helper is for already-validated runs.

pub fn covers(&self, position: usize) -> bool

Returns true if the given absolute position falls inside this run. Returns false if the run’s end overflows usize (such a run is invalid; use validate_and_sort_mm_info before relying on this method).

Trait Implementations

impl Clone for TokenBlockMmInfo

fn clone(&self) -> TokenBlockMmInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TokenBlockMmInfo

impl Debug for TokenBlockMmInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TokenBlockMmInfo

fn deserialize<__D>( __deserializer: __D, ) -> Result<TokenBlockMmInfo, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TokenBlockMmInfo

impl From<RequestMmObjectInfo> for TokenBlockMmInfo

fn from(v: RequestMmObjectInfo) -> Self

Converts to this type from the input type.

impl From<TokenBlockMmInfo> for RequestMmObjectInfo

fn from(v: TokenBlockMmInfo) -> Self

Converts to this type from the input type.

impl Hash for TokenBlockMmInfo

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TokenBlockMmInfo

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
