Trait graph::prelude::ParseValue

pub trait ParseValue: Default + Sized {
    // Required method
    fn parse(bytes: &[u8]) -> (Self, usize);
}

Used by input formats to read node or edge values from bytes.

Required Methods

fn parse(bytes: &[u8]) -> (Self, usize)

Parses a value from a slice.

Example

use graph_builder::input::ParseValue;

let bytes = "13.37".as_bytes();

let (number, len) = f32::parse(bytes);

assert_eq!(number, 13.37);
assert_eq!(len, 5);

Return

Returns a tuple containing two entries. The first is the parsed value, the second is the index of the byte right after the parsed value.

Object Safety

This trait is not object safe.
