Implementations§

source§

impl Setting

source

pub fn key(&self) -> &ConfigKey

The config edited by this setting.

source

pub fn order(&self) -> u16

Position of the setting in a list of settings.

Lower numbers are listed first, two settings with the same order are sorted by display name.

source

pub fn name(&self) -> &BoxedVar<Txt>

Display name.

source

pub fn description(&self) -> &BoxedVar<Txt>

Short help text.

source

pub fn category(&self) -> &CategoryId

Settings category.

source

pub fn meta(&self) -> StateMapRef<'_, Setting>

Custom setting metadata.

source

pub fn value_is_set(&self) -> bool

If the value is set to an actual config variable.

Setting builders can not set the value, this can be used to indicate that the setting must be edited directly on the config file.

source

pub fn value(&self) -> &BoxedAnyVar

Config value.

source

pub fn value_type(&self) -> TypeId

Config value type.

source

pub fn value_downcast<T: ConfigValue>(&self) -> Option<BoxedVar<T>>

Config value, strongly typed.

source

pub fn can_reset(&self) -> BoxedVar<bool>

Gets a variable that indicates the current setting value is not the default.

source

pub fn reset(&self)

Reset the setting value.

source

pub fn search_index(&self, search: &str) -> Option<usize>

Gets if the setting should be included in the search and how likely it is to be an exact match (0 is exact).

If search starts with @key: matches key case sensitive, otherwise matches name or description in lower case. Note that non-key search is expected to already be lowercase.
