Trait read_fonts::FontRead

source ·

pub trait FontRead<'a>: Sized {
    // Required method
    fn read(data: FontData<'a>) -> Result<Self, ReadError>;
}

Expand description

A type that can be read from raw table data.

This trait is implemented for all font tables that are self-describing: that is, tables that do not require any external state in order to interpret their underlying bytes. (Tables that require external state implement FontReadWithArgs instead)

Required Methods§

source

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instace of Self from the provided data, performing validation.

In the case of a table, this method is responsible for ensuring the input data is consistent: this means ensuring that any versioned fields are present as required by the version, and that any array lengths are not out-of-bounds.

Object Safety§

This trait is not object safe.
