Struct ConfigLoader 

pub struct ConfigLoader;

Configuration loader with format detection and parsing.

Implementations

impl ConfigLoader

pub fn load<T: DeserializeOwned>(path: impl AsRef<Path>) -> Result<T>

Load configuration from a file with automatic format detection.

Format is determined by file extension:

• .yaml, .yml -> YAML
• .json -> JSON
• .toml -> TOML

Errors

Returns error if:

• File cannot be read
• Format cannot be determined from extension
• Content fails to parse

pub fn load_with_format<T: DeserializeOwned>( path: impl AsRef<Path>, format: ConfigFormat, ) -> Result<T>

Load configuration from a file with explicit format.

pub fn load_from_reader<T: DeserializeOwned, R: Read>( reader: &mut R, format: ConfigFormat, ) -> Result<T>

Load configuration from a reader with explicit format.

pub fn parse<T: DeserializeOwned>( content: &str, format: ConfigFormat, ) -> Result<T>

Parse configuration from a string with specified format.

pub fn serialize<T: Serialize>( config: &T, format: ConfigFormat, ) -> Result<String>

Serialize configuration to a string.

pub fn save<T: Serialize>(config: &T, path: impl AsRef<Path>) -> Result<()>

Save configuration to a file with automatic format detection.

pub fn save_with_format<T: Serialize>( config: &T, path: impl AsRef<Path>, format: ConfigFormat, ) -> Result<()>

Save configuration to a file with explicit format.

pub fn load_first<T: DeserializeOwned>( paths: &[impl AsRef<Path>], ) -> Result<(T, PathBuf)>

Try to load configuration from multiple paths, returning the first success.

Useful for loading from default locations:

let config: EngineConfig = ConfigLoader::load_first(&[
    "config.yaml",
    "config.json",
    "/etc/trap-sim/config.yaml",
])?;

pub fn is_supported(path: impl AsRef<Path>) -> bool

Check if a file format is supported.
