//! Fast, minimal float-parsing algorithm.
|
|
//!
|
|
//! minimal-lexical has a simple, high-level API with a single
|
|
//! exported function: [`parse_float`].
|
|
//!
|
|
//! [`parse_float`] expects a forward iterator for the integer
|
|
//! and fraction digits, as well as a parsed exponent as an [`i32`].
|
|
//!
|
|
//! For more examples, please see [simple-example](https://github.com/Alexhuszagh/minimal-lexical/blob/master/examples/simple.rs).
|
|
//!
|
|
//! EXAMPLES
|
|
//! --------
|
|
//!
|
|
//! ```
|
|
//! extern crate minimal_lexical;
|
|
//!
|
|
//! // Let's say we want to parse "1.2345".
|
|
//! // First, we need an external parser to extract the integer digits ("1"),
|
|
//! // the fraction digits ("2345"), and then parse the exponent to a 32-bit
|
|
//! // integer (0).
|
|
//! // Warning:
|
|
//! // --------
|
|
//! // Please note that leading zeros must be trimmed from the integer,
|
|
//! // and trailing zeros must be trimmed from the fraction. This cannot
|
|
//! // be handled by minimal-lexical, since we accept iterators.
|
|
//! let integer = b"1";
|
|
//! let fraction = b"2345";
|
|
//! let float: f64 = minimal_lexical::parse_float(integer.iter(), fraction.iter(), 0);
|
|
//! println!("float={:?}", float); // 1.235
|
|
//! ```
