Enum OptionValue 

pub enum OptionValue {
    Bool(bool),
    U32(u32),
    I32(i32),
    F32(f32),
    String(String),
}

Coerced value handed to a codec’s apply method. Codec code chooses the appropriate as_* accessor based on the field name.

Variants

Bool(bool)

A coerced boolean value.

U32(u32)

A coerced unsigned 32-bit integer.

I32(i32)

A coerced signed 32-bit integer.

F32(f32)

A coerced 32-bit float.

String(String)

A string value (also used for OptionKind::Enum matches).

Implementations

impl OptionValue

pub fn as_bool(&self) -> Result<bool>

Extract the boolean, or Error::InvalidData when the value is a different kind.

pub fn as_u32(&self) -> Result<u32>

Extract the u32, or Error::InvalidData when the value is a different kind.

pub fn as_i32(&self) -> Result<i32>

Extract the i32, or Error::InvalidData when the value is a different kind.

pub fn as_f32(&self) -> Result<f32>

Extract the f32, or Error::InvalidData when the value is a different kind.

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

Extract the string (also the shape of Enum matches), or Error::InvalidData when the value is a different kind.
