}This is supported on crate feature
const_new only.Expand description
Creates an inline SmallVec containing the arguments. This macro is enabled by the feature const_new.
smallvec_inline! allows SmallVecs to be defined with the same syntax as array expressions in const contexts.
The inline storage A will always be an array of the size specified by the arguments.
There are two forms of this macro:
- Create a
SmallVeccontaining a given list of elements:
const V: SmallVec<[i32; 3]> = smallvec_inline![1, 2, 3];
assert_eq!(V[0], 1);
assert_eq!(V[1], 2);
assert_eq!(V[2], 3);- Create a
SmallVecfrom a given element and size:
const V: SmallVec<[i32; 3]> = smallvec_inline![1; 3];
assert_eq!(V, SmallVec::from_buf([1, 1, 1]));Note that the behavior mimics that of array expressions, in contrast to smallvec.
