Enum CausalMaskKind 

#[repr(i32)]
pub enum CausalMaskKind {
    kNONE = 0,
    kUPPER_LEFT = 1,
    kLOWER_RIGHT = 2,
}

! ! \enum CausalMaskKind ! ! \brief Enumerates the causal mask alignment orientation for the attention. ! ! When s_q == s_kv, both kUPPER_LEFT and kLOWER_RIGHT produce identical triangular masks. ! When s_q != s_kv (e.g., during LLM generation where s_q=1 and s_kv grows): ! - kUPPER_LEFT: Diagonal anchored at top-left corner (j <= i). Query tokens attend only to the earliest cache ! positions. ! - kLOWER_RIGHT: Diagonal anchored at bottom-right corner (j <= i + (s_kv - s_q)). Query tokens attend to all ! preceding context, which is the correct behavior for autoregressive generation. ! ! \see IAttention::setCausalKind(), IAttention::getCausalKind() !

Variants

kNONE = 0

! No causal masking applied.

kUPPER_LEFT = 1

! Diagonal anchored at top-left corner (legacy default when causal=true).

kLOWER_RIGHT = 2

! Diagonal anchored at bottom-right corner (decode-aligned semantics).

Trait Implementations

impl Clone for CausalMaskKind

fn clone(&self) -> CausalMaskKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CausalMaskKind

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

Formats the value using the given formatter.

impl From<CausalMaskKind> for CausalMaskKind

fn from(value: CausalMaskKind) -> Self

Converts to this type from the input type.

impl Hash for CausalMaskKind

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

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 Into<CausalMaskKind> for CausalMaskKind

fn into(self) -> CausalMaskKind

Converts this type into the (usually inferred) input type.

impl Ord for CausalMaskKind

fn cmp(&self, other: &CausalMaskKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CausalMaskKind

fn eq(&self, other: &CausalMaskKind) -> 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 PartialOrd for CausalMaskKind

fn partial_cmp(&self, other: &CausalMaskKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
