Struct safer_ffi::c_char

#[repr(transparent)]
pub struct c_char(pub u8);

A ReprC standalone type with the same layout and ABI as ::libc::c_char.

By standalone, the idea is that this is defined as a (transparent) newtype struct, rather than as a type alias, which is error-prone and yields less-portable headers (since the header generation will resolve the type alias and emit, for instance, int8_t, ⚠️).

By using this type, you guarantee that the C char type be used in the headers.

Trait Implementations

impl Clone for c_char

fn clone(&self) -> c_char

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for c_char

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for c_char

fn default() -> c_char

Returns the “default value” for a type.

impl Hash for c_char

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LegacyCType for c_char

fn c_short_name_fmt(fmt: &mut Formatter<'_>) -> Result

A short-name description of the type, mainly used to fill “placeholders” such as when monomorphising generics structs or arrays.

fn c_var_fmt(fmt: &mut Formatter<'_>, var_name: &str) -> Result

The core method of the trait: it provides the implementation to be used by [CType::c_var], by bringing a Formatter in scope.

fn c_define_self(_: &mut dyn Definer) -> Result<()>

Necessary one-time code for [CType::c_var]() to make sense.

fn csharp_define_self(_: &mut dyn Definer) -> Result<()>

Extra typedef code (e.g. [LayoutKind.Sequential] struct ...)

fn csharp_ty() -> String

Type name (e.g., int, string, IntPtr)

type OPAQUE_KIND = Concrete

fn c_short_name() -> ImplDisplay<Self>

Convenience function for callers / users of types implementing CType.

fn c_var(var_name: &str) -> ImplDisplay<'_, Self>

Convenience function for callers / users of types implementing CType.

fn legacy_csharp_marshaler() -> Option<String>

Optional marshaler attached to the type (e.g., [MarshalAs(UnmanagedType.FunctionPtr)])

fn csharp_var(var_name: &str) -> String

Convenience function for formatting {ty} {var} in CSharp.

impl Ord for c_char

fn cmp(&self, other: &c_char) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for c_char

fn eq(&self, other: &c_char) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for c_char

fn partial_cmp(&self, other: &c_char) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl ReprC for c_char

type CLayout = c_char

The CType having the same layout as Self.

fn is_valid(_: &Self::CLayout) -> bool

Sanity checks that can be performed on an instance of the CType layout.

impl Copy for c_char

impl Eq for c_char

impl StructuralPartialEq for c_char
