Struct EnvOverride 

#[non_exhaustive]
pub struct EnvOverride {
    pub env_var: String,
    pub target_field: String,
    pub source: EnvOverrideSource,
    pub value: Option<String>,
}

One environment override applied to a configuration struct.

Secret-typed targets redact their value by setting Self::value to None; non-secret targets carry the parsed string value that was applied.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

env_var: String

Environment variable name that supplied the override.

target_field: String

Dotted TOML path that was overridden, such as server.listen_port.

source: EnvOverrideSource

Source of the override value.

value: Option<String>

Applied non-secret value, or None for secret-typed targets.
