pub enum MapHeader {
    Compact(CompactMapHeader),
    Extended(ExtendedMapHeader),
}

Header representing a map of key-value pairs.

Variants

Compact(CompactMapHeader)

Compact header.

Extended(ExtendedMapHeader)

Extended header.

Implementations

impl MapHeader

pub fn compact(len: u8) -> Self

Creates a compact header.

pub fn compact_unchecked(len: u8) -> Self

Creates a compact header, without checking invariants.

pub fn extended(len: usize) -> Self

Creates an extended header.

pub fn for_len(len: usize, packing_mode: PackingMode) -> Self

Creates a header for a given map’s length, for a given packing_mode.

pub fn is_empty(&self) -> bool

Returns true if the associated value has a length of zero, otherwise false.

pub fn len(&self) -> usize

Returns the associated value’s length.

Trait Implementations

impl Clone for MapHeader

fn clone(&self) -> MapHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapHeader

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

Formats the value using the given formatter.

impl From<MapHeader> for Header

fn from(value: MapHeader) -> Self

Converts to this type from the input type.

impl PartialEq for MapHeader

fn eq(&self, other: &MapHeader) -> 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.
