Implementations

impl ValueKind

pub const fn code(self) -> u8

Returns the raw 8-bit kind code.

pub const fn from_code(code: u8) -> Self

Returns a kind from its raw 8-bit code.

Unknown codes map to Unknown.

impl ValueKind

pub const fn is_compact(self) -> bool

Returns whether this kind belongs to the compact universal band.

pub const fn is_nil(self) -> bool

Returns whether this kind represents absence.

pub const fn is_number(self) -> bool

Returns whether this kind represents a numeric scalar.

pub const fn is_scalar(self) -> bool

Returns whether this kind represents a scalar-like atom.

pub const fn is_ref_like(self) -> bool

Returns whether this kind points outside the immediate value body.

pub const fn is_aggregate(self) -> bool

Returns whether this kind describes aggregate data.

pub const fn is_callable(self) -> bool

Returns whether this kind describes callable behavior.

pub const fn is_object(self) -> bool

Returns whether this kind describes a domain-specific body.

pub const fn is_resource(self) -> bool

Returns whether this kind describes an externally managed resource.

pub const fn is_escape(self) -> bool

Returns whether this kind needs profile-specific decoding or widening.

pub const fn is_unknown(self) -> bool

Returns whether this kind is unknown or unmapped.

Trait Implementations
