Implementations

impl txt

pub fn from_str(s: &str) -> Self

FIXME: This method is only used when calling crate::ffi::VSLbt, and current implementation creates a string without a null terminator to pass it in. Going forward, we should probably refactor it to avoid extra string allocation.

pub fn from_cstr(s: &CStr) -> Self

pub fn to_slice(&self) -> Option<&[u8]>

Convert the txt struct to a &[u8]. We want to explicitly differentiate between empty (None) and null (Some([])) strings.

pub fn to_str(&self) -> Option<StrOrBytes<'_>>

Convert the txt struct to a StrOrBytes enum.

pub fn parse_header(&self) -> Option<(&str, StrOrBytes<'_>)>

Parse the txt struct as a header, returning a tuple with the key and value, trimming the value of leading whitespace.
