Struct Validation 

Source 
pub struct Validation {
    pub selection_change: Option<Selection>,
    pub text_change: Option<String>,
    /* private fields */
}
Expand description

The result of a Formatter attempting to validate some partial input.

Fields§

§selection_change: Option<Selection>

A manual selection override.

This will be set as the new selection (regardless of whether or not validation succeeded or failed)

§text_change: Option<String>

A manual text override.

This will be set as the new text, regardless of whether or not validation failed.

Implementations§

Source§
