Struct DrawList 

pub struct DrawList { /* private fields */ }

An encoded drawing command list, ready to go on the wire as one property value.

Cloning shares the bytes, and equality compares them, so a frame that rebuilds the same list produces no SetProp at all: the runtime compares the attribute and skips it.

Implementations

impl DrawList

pub fn builder() -> DrawListBuilder

pub fn from_bytes(bytes: impl Into<Rc<[u8]>>) -> Self

Adopts an already encoded list, which is what the protocol vectors carry.

pub fn as_bytes(&self) -> &[u8]

pub fn is_empty(&self) -> bool

pub fn decode(&self) -> Result<Vec<DrawCommand>, ProtocolError>

The commands, in order. Errors if the bytes are not a well-formed list.

pub fn text_at(&self, offset: u32, length: u32) -> Result<&str, ProtocolError>

The string a TextAt command points at.
