Trait for the editor widget state

Required Associated Types

type Context<'a>

Some external context.

type Value: Clone

Type of data.

type Err

Error type.

Required Methods

fn create_value<'a>( &self, ctx: &'a Self::Context<'a>, ) -> Result<Self::Value, Self::Err>

Create a fresh value with all the defaults.

fn set_value<'a>( &mut self, value: Self::Value, ctx: &'a Self::Context<'a>, ) -> Result<(), Self::Err>

Set the current value for the editor.

fn value<'a>( &mut self, ctx: &'a Self::Context<'a>, ) -> Result<Option<Self::Value>, Self::Err>

Return the current value from the editor.

fn focused_col(&self) -> Option<usize>

Returns the currently focused column. Used to scroll the column to fully visible.

fn set_focused_col(&self, col: usize)

Allows setting the focus for the editor.

This trait is not dyn compatible.

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