Struct ffishim::types::String

pub struct String;

The std lib's String type behavior.

We currently use a CString from to ingest all String values. This might be unsafe if the string was instantiated by the caller without using rust's instanciation mechanism. In that case, it would be safe to use a CStr. See https://doc.rust-lang.org/std/ffi/struct.CString.html

Trait Implementations

impl Behavior for Behavior

fn is(&self, sty: &Type) -> bool

Returns true if this behavior is fit to handle the given sty.

fn fold(&self, _: Type) -> Type

Transforms the given Type into its shim equivalent. For example: - String -> *mut libc::c_char - u32 -> libc::c_uint - ...

fn try_into(&self, _: &Type, expr: Expr) -> Expr

Returns an Expression that mutates the shim type into the original one.

fn from(&self, _: &Type, expr: Expr) -> Expr

Returns an Expression that mutates the original type into its shim equivalent.

fn free(&self, _: &Type, expr: Expr) -> Option<Expr>

Returns an Expression that frees an expression of the given type.
