Implementations

impl ConfigValue

pub const fn as_bool(&self) -> Option<bool>

Returns the boolean value, if this is a boolean.

pub const fn as_i64(&self) -> Option<i64>

pub const fn as_f64(&self) -> Option<f64>

Returns the floating-point value, if this is a float.

pub fn as_str(&self) -> Option<&str>

Returns the string value, if this is a string.

pub fn as_list(&self) -> Option<&[ConfigValue]>

Returns the list value, if this is a list.

pub const fn as_map(&self) -> Option<&BTreeMap<String, ConfigValue>>

Returns the map value, if this is a map.
