Function stringzilla::sz::find

pub fn find<H, N>(haystack: H, needle: N) -> Option<usize>
where
    H: AsRef<[u8]>,
    N: AsRef<[u8]>,

Locates the first matching substring within haystack that equals needle. This function is similar to the memmem() function in LibC, but, unlike strstr(), it requires the length of both haystack and needle to be known beforehand.

Arguments

• haystack: The byte slice to search.
• needle: The byte slice to find within the haystack.

Returns

An Option<usize> representing the starting index of the first occurrence of needle within haystack if found, otherwise None.
