Enum casper_node::utils::External [−][src]
External resource.
An External resource can be given in two ways: Either as an immediate value, or through a
path, provided the value implements Loadable.
Serializing and deserializing an External value is only possible if it is in path form. This
is especially useful when writing structure configurations.
An External also always provides a default, which will always result in an error when load
is called. Should the underlying type T implement Default, the with_default can be
used instead.
Variants
Path(PathBuf)Value that should be loaded from an external path.
Loaded or immediate value.
The value has not been specified, but a default has been requested.
Implementations
impl<T> External<T>[src]
pub fn from_value(value: T) -> Self[src]
Creates an external from a value.
pub fn from_path<P: AsRef<Path>>(path: P) -> Self[src]
Creates an external referencing a path.
impl<T> External<T> where
T: Loadable, [src]
T: Loadable,
pub fn load<P: AsRef<Path>>(self, root: P) -> Result<T, LoadError<T::Error>>[src]
Loads the value if not loaded already, resolving relative paths from root or returns
available value. If the value is Missing, returns an error.
pub fn full_path<P: AsRef<Path>>(&self, root: P) -> Option<PathBuf>[src]
Returns the full path to the external item, or None if the type is Loaded or Missing.
impl<T> External<T> where
T: Loadable + Default, [src]
T: Loadable + Default,
pub fn with_default(self) -> Self[src]
Insert a default value if missing.
