:mrdocs:

The return result of a string‐to‐number conversion.

== Synopsis

Declared in `<absl/strings/charconv.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
struct from_chars_result;
----

== Description

`ec` will be set to `invalid_argument` if a well‐formed number was not found at the start of the input range, `result_out_of_range` if a well‐formed number was found, but it was out of the representable range of the requested type, or to std::errc() otherwise.

If a well‐formed number was found, `ptr` is set to one past the sequence of characters that were successfully parsed. If none was found, `ptr` is set to the `first` argument to from_chars.
