Trait FromString

pub trait FromString: Sized {
    // Required method
    fn from_string(s: String) -> Result<Self, Error>;
}

Parse a value from an owned string

FromString is implemented for all compatible FromStr types. Those are all types with an implementation that fails with an error that can be converted into a Box<dyn Error + Send + Sync>.

This trait cannot be be implemented for custom types because of the blanket implementation. A more ergonomic way to call this is the from_string function.

Required Methods

fn from_string(s: String) -> Result<Self, Error>

Parses a string `s`` to return a value of this type.

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.
