Implementations

impl FieldPos

pub fn new_not_present() -> Self

pub fn build(msg_buf: &[u8], field_buf: &str) -> Option<Self>

pub fn new<T>(msg_buf: &[u8], field: Option<&T>) -> Self

where T: Deref<Target = str>,

pub fn read<'m, T>(&self, msg_buf: &'m [u8]) -> Option<T>

where T: TryFrom<&'m str>, T::Error: Debug,

Reassemble a previously cached field.

NOTE: The caller must ensure that the msg_buff is the same one build was called for. Otherwise, you’ll get a panic.
