Enum Usage 

pub enum Usage {
    Stream,
    Static,
    Dynamic,
}

Used to hint to the implementation how frequently the user will be changing the buffer’s data.

• Static: The user will set the data once.
• Dynamic: The user will set the data occasionally.
• Stream: The user will be changing the data after every use. Or almost every use.

Variants

Trait Implementations

impl Clone for Usage

fn clone(&self) -> Usage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Usage

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

Formats the value using the given formatter.

impl PartialEq for Usage

fn eq(&self, other: &Usage) -> 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 Copy for Usage

impl Eq for Usage

impl StructuralPartialEq for Usage
