Struct CanvasRenderTask 

pub struct CanvasRenderTask<'m, 't, Feat: ExportFeature> {
    pub module: &'m Module,
    pub use_stable_glyph_id: bool,
    /* private fields */
}

Holds the data for rendering canvas.

The ’m lifetime is the lifetime of the module which stores the frame data. The ’t lifetime is the lifetime of SVG task.

Fields

module: &'m Module

The module which stores the frame data.

use_stable_glyph_id: bool

See ExportFeature.
