Struct OptionCapabilityProfile 

pub struct OptionCapabilityProfile {
    pub dom: bool,
    pub canvas: bool,
    pub webgl: bool,
    pub webgpu: bool,
    pub true_color: bool,
    pub max_scrollback_lines: u32,
}

What the active rendering engine / host advertises as supported. A schema-valid option can still be gated against this profile.

Fields

dom: bool

Whether the DOM renderer is available (effectively always true).

canvas: bool

Whether the 2D canvas renderer is available.

webgl: bool

Whether the WebGL renderer is available.

webgpu: bool

Whether the WebGPU renderer is available.

true_color: bool

Whether 24-bit colour is supported (informational; theme colours stay host-downgraded rather than gated).

max_scrollback_lines: u32

Maximum scrollback the host will retain in memory.

Implementations

impl OptionCapabilityProfile

pub const fn minimal() -> Self

A conservative default profile: DOM + Canvas only, modest scrollback.

pub const fn full() -> Self

A fully-featured profile: every renderer, generous scrollback.

pub const fn supports_renderer(&self, renderer: RendererType) -> bool

Whether the requested renderer backend is available.

Trait Implementations

impl Clone for OptionCapabilityProfile

fn clone(&self) -> OptionCapabilityProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OptionCapabilityProfile

impl Debug for OptionCapabilityProfile

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

Formats the value using the given formatter.

impl Default for OptionCapabilityProfile

fn default() -> Self

Returns the “default value” for a type.

impl Eq for OptionCapabilityProfile

impl PartialEq for OptionCapabilityProfile

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