Implementations

impl FixString

pub const fn new() -> FixString

pub fn with_capacity(capacity: usize) -> FixString

pub fn from_ascii(buf: Vec<u8>) -> Result<FixString, FixStringError>

Converts a vector of bytes to a FixString.

A FIX string (FixString) is made of bytes (u8), and a vector of bytes (Vec<u8>) is made of bytes, so this function converts between the two. Not all byte slices are valid FixStrings, however: FixString requires that it is valid ASCII. from_ascii() checks to ensure that the bytes are valid ASCII, and then does the conversion.

If you are sure that the byte slice is valid ASCII, and you don’t want to incur the overhead of the validity check, there is an unsafe version of this function, from_ascii_unchecked, which has the same behavior but skips the check.

This method will take care to not copy the vector, for efficiency’s sake.

If you need a &FixStr instead of a FixString, consider FixStr::from_ascii.

The inverse of this method is into_bytes.

Errors

Returns Err if the slice is not ASCII with a description as to why the provided bytes are not ASCII.

pub unsafe fn from_ascii_unchecked(buf: Vec<u8>) -> FixString

Converts a vector of bytes to a FixString without checking that the it contains only ASCII characters.

See the safe version, from_ascii, for more details.

Safety

This function is unsafe because it does not check that the bytes passed to it are valid ASCII. If this constraint is violated, it may cause memory unsafety issues with future users of the FixString, as the rest of the library assumes that FixStrings are valid ASCII.

pub fn from_ascii_lossy(buf: Vec<u8>) -> FixString

Converts a slice of bytes to a FixString, replacing invalid characters by ?.
