Method from_str_with_schema

alpm-srcinfo/src/source_info/mod.rs:212–226

Creates a [`SourceInfo`] from string slice, optionally validated using a [`SourceInfoSchema`]. If `schema` is [`None`] attempts to detect the [`SourceInfoSchema`] from `s`. Attempts to create a [`SourceInfo`] variant that corresponds to the [`SourceInfoSchema`]. # Note To automatically derive the [`SourceInfoSchema`], use [`SourceInfo::from_str`]. # Examples ``` use std::{fs::File, io::Write}

(s: &str, schema: Option<SourceInfoSchema>)

    ///   - a [`SourceInfoSchema`] cannot be derived from `s`,
    ///   - or the detected variant of [`SourceInfo`] cannot be constructed from `s`.
    fn from_str_with_schema(s: &str, schema: Option<SourceInfoSchema>) -> Result<Self, Error> {
        // NOTE: This does not use `SourceInfoSchema::derive_from_str`,
        // to not run the parser twice.
        // In the future, this should run `SourceInfoContent` parser directly
        // and delegate to `from_raw` instead of `from_string`.
