Trait Renderer 

pub trait Renderer {
    type Output;

    // Required method
    fn render(
        &self,
        symbol: &Symbol,
        options: &RenderOptions,
    ) -> Result<Self::Output>;
}

Draws a Symbol into some output representation.

Implementations must honour the shared Layout so that all output formats stay geometrically identical.

Required Associated Types

type Output

What this renderer produces — Vec<u8> for PNG, String for SVG.

Required Methods

fn render( &self, symbol: &Symbol, options: &RenderOptions, ) -> Result<Self::Output>

Render symbol.

Errors

Returns Error::InvalidRenderOptions if the geometry is unusable, or Error::Render if the underlying encoder fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
