Struct Select 

pub struct Select<T> { /* private fields */ }

A field that selects one value from a non-empty list of options.

Implementations

impl<T> Select<T>

pub fn new( key: FieldKey<T>, question: impl Into<String>, options: Vec<SelectOption<T>>, ) -> Result<Self, FieldConfigError>

Creates a select field with the first option initially selected.

pub fn help(self, help: impl Into<String>) -> Self

Sets the navigation hint shown beneath the options. help is plain text. Escape sequences in it are counted as ordinary characters when the prompt measures its cells, so a pre-styled string mis-aligns the field; style it through the prompt’s theme instead.

pub fn description(self, description: impl Into<String>) -> Self

Sets supporting text shown below the question. description is plain text. Escape sequences in it are counted as ordinary characters when the prompt measures its cells, so a pre-styled string mis-aligns the field; style it through the prompt’s theme instead.

pub fn filter_help( self, editing: impl Into<String>, applied: impl Into<String>, ) -> Self

Sets the hints shown while editing and after applying a filter.

pub fn no_matches_message(self, message: impl Into<String>) -> Self

Sets the message shown when filtering removes every option.

pub fn visible_rows(self, rows: usize) -> Self

Limits the number of option rows shown before the list scrolls.
