There is a function float_s
that parses floats in stream mod (can return Incomplete
). I want to use CompleteStr
as input type instead. How I can achieve that?
Simple approach fails with complains about &str
and CompleteStr
mismatches:
named!(parse_float_complete(CompleteStr) -> f32,
ws!(::num::float_s)
);
I'm using nom 4.0.0
.
nom v4.1.0
fixed this problem:
float
and double
now work on all of nom's input types ( &[u8]
, &str
, CompleteByteSlice
, CompleteStr
and any type that implements the required traits). float_s
and double_s
got the same modification, but are now deprecated float_s
expects a string, so you have to extract the string from the CompleteStr
:
named!(parse_float_complete(CompleteStr) -> f32,
ws!(call!(|input| ::num::float_s(input.0).map(|output, result| CompleteStr(output, result))))
);
My current workaround is to just copy-paste float_s
implementation:
fn float_cs(input: CompleteStr) -> ::nom::IResult<CompleteStr, f32> {
flat_map!(input, call!(::nom::recognize_float), parse_to!(f32))
}
