Enum MmapHint

pub enum MmapHint {
    Never,
    Always,
    Threshold(usize),
}

Hint for specifying whether font files should be memory mapped.

Variants

Never

Never memory map.

Always

Always memory map.

Threshold(usize)

Memory map when file size is greater than or equal to a threshold value.

Trait Implementations

impl Clone for MmapHint

fn clone(&self) -> MmapHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MmapHint

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

Formats the value using the given formatter.

impl Default for MmapHint

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for MmapHint

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