Enum Intent 

pub enum Intent {
    Create,
    Update,
}

Whether the caller is building a new surface or editing one that exists.

Variants

Create

Build a surface that does not exist yet.

Update

Edit a surface the renderer already holds.

Implementations

impl Intent

pub fn from_wire(value: &str) -> Option<Self>

Parses the wire spelling, case-insensitively.

Anything unrecognized is None rather than a silent default: guessing wrong in the “update” direction re-creates a live surface.

pub fn as_str(self) -> &'static str

The wire spelling.

pub fn needs_create_surface(self) -> bool

Whether a createSurface operation belongs in this stream.

Trait Implementations

impl Clone for Intent

fn clone(&self) -> Intent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Intent

impl Debug for Intent

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

Formats the value using the given formatter.

impl Default for Intent

fn default() -> Intent

Returns the “default value” for a type.

impl Display for Intent

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

Formats the value using the given formatter.

impl Eq for Intent

impl PartialEq for Intent

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