Enum ClassToken 

pub enum ClassToken {
    Start,
    Middle,
    End,
    Custom(usize),
}

Position marker for a learnable class token inserted into a network’s input sequence (embedding width = the network input width / “d_input”).

Variants

Start

Prepend before the whole sequence (index 0).

Middle

Insert at the middle of the original sequence (index L/2).
Incompatible with step() calls.

End

Append after the whole sequence (index L).
Incompatible with step() calls.

Custom(usize)

Insert at an explicit index into the original sequence.

Trait Implementations

impl ClassMarker for ClassToken

fn insert_pos(&self, orig_len: usize) -> usize

Insertion index measured against the original sequence length orig_len.

fn group_rank(&self) -> usize

Tie-break rank among markers sharing an index (Start<Middle<End<Custom).

fn forbids_step(&self) -> bool

Whether this marker is incompatible with single-token step() (Middle/End create positions a per-token recurrence cannot reproduce).

impl Clone for ClassToken

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Config for ClassToken

fn load_binary(data: &[u8]) -> Result<Self, ConfigError>

Loads the configuration from a binary buffer.

impl Debug for ClassToken

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClassToken

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ClassToken

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

Formats the value using the given formatter.

impl Serialize for ClassToken

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
