Struct LowPriorityEnvSource 

pub struct LowPriorityEnvSource { /* private fields */ }

Available on crate feature conf and non-WebAssembly only.

Low-priority environment variable configuration source

This wrapper provides the same functionality as EnvSource but with lower priority than TOML files, allowing TOML configuration to override environment variables.

Priority: 40 (lower than TOML files at 50)

Examples

use reinhardt_conf::settings::sources::LowPriorityEnvSource;
use reinhardt_conf::settings::builder::SettingsBuilder;

let settings = SettingsBuilder::new()
    .add_source(LowPriorityEnvSource::new())
    .build()
    .unwrap();

Implementations

impl LowPriorityEnvSource

pub fn new() -> LowPriorityEnvSource

Create a new low-priority environment variable configuration source

Examples

use reinhardt_conf::settings::sources::LowPriorityEnvSource;

let source = LowPriorityEnvSource::new();

pub fn with_prefix(self, prefix: impl Into<String>) -> LowPriorityEnvSource

Set a prefix filter for environment variables

Examples

use reinhardt_conf::settings::sources::LowPriorityEnvSource;

let source = LowPriorityEnvSource::new()
    .with_prefix("REINHARDT_");

pub fn with_interpolation(self, enabled: bool) -> LowPriorityEnvSource

Enable variable interpolation for environment values

Examples

use reinhardt_conf::settings::sources::LowPriorityEnvSource;

let source = LowPriorityEnvSource::new()
    .with_interpolation(true);
