Struct gv100ad::parser::FieldReader [−][src]
Reader to read fields from a single data record (i.e. line). Specifically this makes sure that data is read correctly as UTF-8.
Implementations
impl<'a> FieldReader<'a>[src]
pub fn new(line: &'a str) -> Self[src]
Creates a new field reader from a single line. It expects the line to not contain any line terminator.
pub fn next(&mut self, n: usize) -> &str[src]
Reads a field of length n as string. n is in characters, not bytes.
pub fn next_opt(&mut self, n: usize) -> Option<&str>[src]
pub fn parse_next<T: FromStr>(
&mut self,
n: usize
) -> Result<T, <T as FromStr>::Err>[src]
&mut self,
n: usize
) -> Result<T, <T as FromStr>::Err>
Reads a field of length n and parses it as T.
pub fn parse_next_opt<T: FromStr>(
&mut self,
n: usize
) -> Result<Option<T>, <T as FromStr>::Err>[src]
&mut self,
n: usize
) -> Result<Option<T>, <T as FromStr>::Err>
pub fn skip(&mut self, n: usize)[src]
Skips n characters.
