Struct jrsonnet_parser::ParamsDesc [−][src]
Expand description
Defined function parameters
Methods from Deref<Target = Vec<Param>>
Returns the number of elements the vector can hold without reallocating.
Examples
let vec: Vec<i32> = Vec::with_capacity(10); assert_eq!(vec.capacity(), 10);
Extracts a slice containing the entire vector.
Equivalent to &s[..]
.
Examples
use std::io::{self, Write}; let buffer = vec![1, 2, 3, 5, 8]; io::sink().write(buffer.as_slice()).unwrap();
Returns a raw pointer to the vector’s buffer.
The caller must ensure that the vector outlives the pointer this function returns, or else it will end up pointing to garbage. Modifying the vector may cause its buffer to be reallocated, which would also make any pointers to it invalid.
The caller must also ensure that the memory the pointer (non-transitively) points to
is never written to (except inside an UnsafeCell
) using this pointer or any pointer
derived from it. If you need to mutate the contents of the slice, use as_mut_ptr
.
Examples
let x = vec![1, 2, 4]; let x_ptr = x.as_ptr(); unsafe { for i in 0..x.len() { assert_eq!(*x_ptr.add(i), 1 << i); } }
🔬 This is a nightly-only experimental API. (allocator_api
)
allocator_api
)Returns a reference to the underlying allocator.
Returns the number of elements in the vector, also referred to as its ‘length’.
Examples
let a = vec![1, 2, 3]; assert_eq!(a.len(), 3);
