Struct VariantType

Source
pub struct VariantType { /* private fields */ }
Expand description

Describes Variant types.

The Variant type system (based on the D-Bus one) describes types with “type strings”. VariantType is an owned immutable type string (you can think of it as a Box<str> statically guaranteed to be a valid type string), &VariantTy is a borrowed one (like &str).

Implementations§

Source§

impl VariantType

Source

pub fn new(type_string: &str) -> Result<VariantType, ()>

Tries to create a VariantType from a string slice.

Returns Ok if the string is a valid type string, Err otherwise.

Methods from Deref<Target = VariantTy>§

Source

pub fn to_str(&self) -> &str

Converts to a string slice.
