[−][src]Trait wasihost::StringRepresentation

pub trait StringRepresentation: 'static + Send + Sync + Deref {
    fn from_bytes(bytes: Vec<u8>) -> Result<Self, ()>;
    fn as_bytes(&self) -> &[u8];
}

A string representation for the WASI high level APIs.

Required methods

`fn from_bytes(bytes: Vec<u8>) -> Result<Self, ()>`

Tries to convert a vector of owned bytes into a string. If the conversion fails, the WASI method that attempted the conversion will return errno_inval.

`fn as_bytes(&self) -> &[u8]`

Converts a string into a byte slice.
