WebJan 26, 2024 · It is needed because Rust loves exposing physical layout of bytes in memory as an interface, specifically for cases where that brings performance. In particular, the meaning of Pathis not that it is some abstract representation of a file path, but that it is just literally a bunch of contiguous bytes in memory. WebReserves the minimum capacity for the given BitSet to contain len distinct elements. In the case of BitSet this means reallocations will not occur as long as all inserted elements are less than len.. Note that the allocator may give the collection more space than it requests. Therefore capacity can not be relied upon to be precisely minimal. hippi tester

Webchar is just a type that can represent any Unicode character, so it needs to be 4 bytes large, but it's not directly tied to the representation of characters in a str .

Byte strings are just like standard Unicode strings with one very important difference: byte strings are only conventionally UTF-8 while Rust’s standard Unicode strings are guaranteed to be valid UTF-8. The primary motivation for byte strings is for handling arbitrary bytes that are mostly UTF-8.

WebConverts a slice of bytes to a string slice. A string slice (&str) is made of bytes (u8), and a byte slice (&[u8]) is made of bytes, so this function converts between the two.Not all byte slices are valid string slices, however: &str requires that it is valid UTF-8. from_utf8() checks to ensure that the bytes are valid UTF-8, and then does the conversion.
