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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
