Deserializer

cargo::util::context::de

Struct Deserializer 

Source 
pub(super) struct Deserializer<'gctx> {
    pub(super) gctx: &'gctx GlobalContext,
    pub(super) key: ConfigKey,
    pub(super) env_prefix_ok: bool,
}
Expand description

Serde deserializer used to convert config values to a target type using GlobalContext::get.

Fields§

§gctx: &'gctx GlobalContext§key: ConfigKey

The current key being deserialized.

§env_prefix_ok: bool

Whether or not this key part is allowed to be an inner table. For example, profile.dev.build-override needs to check if CARGO_PROFILE_DEV_BUILD_OVERRIDE_ prefixes exist. But CARGO_BUILD_TARGET should not check for prefixes because it would collide with CARGO_BUILD_TARGET_DIR. See ConfigMapAccess for details.
