Struct ocaml::OCaml[−][src]

pub struct OCaml<'a, T> where
    T: 'a,  { /* fields omitted */ }

Representation of OCaml values.

Implementations

impl<'a, T> OCaml<'a, T>[src]

pub fn as_ref<'b>(&'b self) -> &'b OCamlCell<T> where
    'a: 'b, [src]

Obtains an OCamlRef<T> for this value.

pub fn root(self) -> BoxRoot<T>[src]

pub unsafe fn raw(&self) -> isize[src]

Gets the raw representation for this value reference (pointer or int).

Safety

The resulting raw pointer will not be tracked, and may become invalid after any call into the OCaml runtime. Great care must be taken when working with these values.

pub fn to_rust<RustT>(&self) -> RustT where
    RustT: FromOCaml<T>, [src]

Converts this OCaml value into a Rust value.

pub unsafe fn custom_ptr_val<U>(&self) -> *const U[src]

Meant to match Data_custom_val from mlvalues.h

Experimental

Safety

Casts to an arbitrary pointer type, take care before dereferencing

Similar to raw(), the resulting pointer can become invalid after any call into the OCaml runtime, for example allocating OCaml values or calling OCaml functions

impl<'a, T> OCaml<'a, DynBox<T>> where
    T: 'static, [src]

pub fn box_value(cr: &'a mut OCamlRuntime, v: T) -> OCaml<'a, DynBox<T>>[src]

Build an OCaml value wrapping a Rust value

The returned value will be opaque to the OCaml side, though you can provide functions using it and expose them to OCaml.

It will be dropped if it stops being referenced by the GC.

Experimental

impl OCaml<'static, ()>[src]

pub fn unit() -> OCaml<'static, ()>[src]

Returns a value that represent OCaml’s unit value.

impl<T> OCaml<'static, Option<T>>[src]

pub fn none() -> OCaml<'static, Option<T>>[src]

Returns a value that represent OCaml’s None value.

impl<'a> OCaml<'a, String>[src]

pub fn as_bytes(&self) -> &'a [u8][src]

Returns an [u8] reference to the internal bytes of this value.

pub fn as_str(&self) -> &'a str[src]

Returns a str reference to the internal bytes of this value.

Panics

Panics if the bytes do not form a valid utf8 string.

pub unsafe fn as_str_unchecked(&self) -> &'a str[src]

Returns a str reference to the internal bytes of this value.

Safety

No checks are performed to ensure that the returned value is a valid utf8 string.

impl<'a> OCaml<'a, OCamlBytes>[src]

pub fn as_bytes(&self) -> &'a [u8][src]

Returns an [u8] reference to the internal bytes of this value.

pub fn as_str(&self) -> &'a str[src]

Returns a str reference to the internal bytes of this value.

Panics

Panics if the bytes do not form a valid utf8 string.

pub unsafe fn as_str_unchecked(&self) -> &'a str[src]

Returns a str reference to the internal bytes of this value.

Safety

No checks are performed to ensure that the returned value is a valid utf8 string.

impl<'a> OCaml<'a, isize>[src]

pub fn to_i64(&self) -> i64[src]

Converts an OCaml int to an i64.

pub unsafe fn of_i64_unchecked(n: i64) -> OCaml<'static, isize>[src]

Creates an OCaml int from an i64 without checking that it fits in an OCaml fixnum.

Safety

OCaml ints are represented as 63bits + 1bit tag, so when converting from an i64, a bit of precision is lost.

pub fn of_i64(
    n: i64
) -> Result<OCaml<'static, isize>, OCamlFixnumConversionError>[src]

pub fn of_i32(n: i32) -> OCaml<'static, isize>[src]

pub fn is_some(&self) -> bool[src]

Returns true if this OCaml option value is an OCaml Some.

pub fn to_option(&self) -> Option<OCaml<'a, A>>[src]

pub fn is_empty(&self) -> bool[src]

pub fn tl(&self) -> Option<OCaml<'a, OCamlList<A>>>[src]
