Trait FromConfig 

pub trait FromConfig: Sized {
    // Required method
    fn from_config(
        property: &Property,
        ctx: &ConfigParseContext<'_>,
    ) -> ConfigResult<Self>;
}

Parses a configuration Property into a target Rust type.

Required Methods

fn from_config( property: &Property, ctx: &ConfigParseContext<'_>, ) -> ConfigResult<Self>

Parses property using ctx.

Parameters

• property - Non-empty property selected by the reader.
• ctx - Key, options, and substitution context.

Returns

Parsed value, or a crate::ConfigError with key context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
