sourcepub async fn verify_detached<M>(
&self,
signature: BinDataSized<64>,

) -> LairResult<bool>

Treat this bin data as an ed25519 public key, and use it to verify a signature over a given message.
Methods from Deref<Target = [u8; N]>§
sourcepub fn as_ascii(&self) -> Option<&[AsciiChar; N]>
🔬This is a nightly-only experimental API. (ascii_char
)
pub fn as_ascii(&self) -> Option<&[AsciiChar; N]>
ascii_char
)Converts this array of bytes into a array of ASCII characters,
or returns None
if any of the characters is non-ASCII.
§Examples
#![feature(ascii_char)]
#![feature(const_option)]
const HEX_DIGITS: [std::ascii::Char; 16] =
*b"0123456789abcdef".as_ascii().unwrap();
assert_eq!(HEX_DIGITS[1].as_str(), "1");
assert_eq!(HEX_DIGITS[10].as_str(), "a");
sourcepub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]
🔬This is a nightly-only experimental API. (ascii_char
)
pub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]
ascii_char
)Converts this array of bytes into a array of ASCII characters, without checking whether they’re valid.
§Safety
Every byte in the array must be in 0..=127
, or else this is UB.
1.57.0 · sourcepub fn as_slice(&self) -> &[T]
pub fn as_slice(&self) -> &[T]
Returns a slice containing the entire array. Equivalent to &s[..]
.
1.77.0 · sourcepub fn each_ref(&self) -> [&T; N]
pub fn each_ref(&self) -> [&T; N]
Borrows each element and returns an array of references with the same
size as self
.
§Example
let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);
This method is particularly useful if combined with other methods, like
map
. This way, you can avoid moving the original
array if its elements are not Copy
.
let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());
assert_eq!(is_ascii, [true, false, true]);
// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);
sourcepub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])
🔬This is a nightly-only experimental API. (split_array
)
pub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])
split_array
)Divides one array reference into two at an index.
The first will contain all indices from [0, M)
(excluding
the index M
itself) and the second will contain all
indices from [M, N)
(excluding the index N
itself).
§Panics
Panics if M > N
.
§Examples
#![feature(split_array)]
let v = [1, 2, 3, 4, 5, 6];
{
let (left, right) = v.split_array_ref::<0>();
assert_eq!(left, &[]);
assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}
{
let (left, right) = v.split_array_ref::<2>();
assert_eq!(left, &[1, 2]);
assert_eq!(right, &[3, 4, 5, 6]);
}
{
let (left, right) = v.split_array_ref::<6>();
assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
assert_eq!(right, &[]);
}
sourcepub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])
🔬This is a nightly-only experimental API. (split_array
)
pub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])
split_array
)Divides one array reference into two at an index from the end.
The first will contain all indices from [0, N - M)
(excluding
the index N - M
itself) and the second will contain all
indices from [N - M, N)
(excluding the index N
itself).
§Panics
Panics if M > N
.
§Examples
#![feature(split_array)]
let v = [1, 2, 3, 4, 5, 6];
{
let (left, right) = v.rsplit_array_ref::<0>();
assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
assert_eq!(right, &[]);
}
{
let (left, right) = v.rsplit_array_ref::<2>();
assert_eq!(left, &[1, 2, 3, 4]);
assert_eq!(right, &[5, 6]);
}
{
let (left, right) = v.rsplit_array_ref::<6>();
assert_eq!(left, &[]);
assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}
