Struct manaconf::Section

pub struct Section<'a> { /* fields omitted */ }

A section of configuration

This acts as a pre-applied prefix to a config key when fetching values

Example

let section = config.section("My::Config::Section");
// This is now the same as requesting `My::Config::Section::Value`
let value: String = section.get_value("Value");

Implementations

impl<'a> Section<'a>

pub fn section<K: AsRef<Key>>(&self, key: K) -> Section

Creates a further subsection from this section, similar to a section created by calling Config::section, except in this case the current sections prefix is prepended to the key passed into section

Example

let section = config.section("first");
let subsection = section.section("second");
// Will read value from "first::second::value"
let value: String = subsection.get_value("value");

Trait Implementations

impl<'a> ValueRead for Section<'a>

fn get_value<T, K>(&self, key: K) -> Result<Option<T>, ValueReadError> where
    K: AsRef<Key>,
    T: TryFromValue, 

Gets a value from configuration using the given key

fn get_expected_value<T, K>(&self, key: K) -> Result<T, ValueReadError> where
    K: AsRef<Key>,
    T: TryFromValue, 

Gets a value from configuration using the given key where the value is expected to exist, and thus it's an error if it doesn't.

fn bind<T: TryFromValueRead>(&self) -> Result<T, ValueReadError>

Bind values to type T
