Trait ConfigBuilder 

pub trait ConfigBuilder: Sized {
    // Required methods
    fn name(&self) -> &str;
    fn version(&self) -> &str;
    fn with_name(self, name: impl Into<String>) -> Self;
    fn with_version(self, version: impl Into<String>) -> Self;
    fn with_config_dir(self, dir: impl Into<PathBuf>) -> Self;
    fn with_config_filename(self, filename: impl Into<String>) -> Self;
}

Assemble application configuration from named sources.

ConfigBuilder is a builder-chain trait – it covers only the configuration fields (name, version, with_config_dir, with_config_filename). It deliberately does not include build_loader(). That finaliser is an inherent method on the concrete builder types (see configbuilder-svc-saf) because the construction logic depends on real filesystem/XDG internals this trait itself must not reference.

Required Methods

fn name(&self) -> &str

Return the configured application name.

fn version(&self) -> &str

Return the configured application version.

fn with_name(self, name: impl Into<String>) -> Self

Set the application name; used by build_loader to resolve XDG paths.

fn with_version(self, version: impl Into<String>) -> Self

Set the application version string.

fn with_config_dir(self, dir: impl Into<PathBuf>) -> Self

Append an explicit config directory; takes precedence over XDG resolution.

Multiple calls accumulate directories – later entries win on key conflicts.

fn with_config_filename(self, filename: impl Into<String>) -> Self

Override the config filename searched for in each configured directory.

Defaults to application.toml when not called.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
