Struct String

Source
pub struct String<'a>(/* private fields */);
Expand description

A reference to a text string.

Implementations§

Source§

impl<'a> String<'a>

Source

pub const unsafe fn new(data: &'a str) -> Self

Wraps a string in a string external reference.

§Safety

It is not actually unsafe to construct a String object. However, if the caller then CBOR-encodes the resulting object, they must ensure that the String object remains in existence until the CBOR data has been submitted as part of a method call. Failure to do this would allow the referent to be modified or dropped, resulting in OC-Wasm reading from that reused memory.
