Trait FromGodot
pub trait FromGodot: Sized + GodotConvert {
// Required method
fn try_from_godot(via: Self::Via) -> Result<Self, ConvertError>;
// Provided methods
fn from_godot(via: Self::Via) -> Self { ... }
fn try_from_variant(variant: &Variant) -> Result<Self, ConvertError> { ... }
fn from_variant(variant: &Variant) -> Self { ... }
}Expand description
Defines the canonical conversion from Godot for a type.
It is assumed that all the methods return equal values given equal inputs. Additionally, it is assumed
that if ToGodot is implemented, converting to Godot and back again will return a value equal to the
starting value.
Violating these assumptions is safe but will give unexpected results.
Please read the godot::meta module docs for further information about conversions.
Required Methods§
fn try_from_godot(via: Self::Via) -> Result<Self, ConvertError>
fn try_from_godot(via: Self::Via) -> Result<Self, ConvertError>
Converts the Godot representation to this type, returning Err on failure.
Provided Methods§
fn from_godot(via: Self::Via) -> Self
fn from_godot(via: Self::Via) -> Self
fn try_from_variant(variant: &Variant) -> Result<Self, ConvertError>
fn try_from_variant(variant: &Variant) -> Result<Self, ConvertError>
Performs the conversion from a Variant, returning Err on failure.
fn from_variant(variant: &Variant) -> Self
fn from_variant(variant: &Variant) -> Self
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
