Extension trait for Dictionary to provide typed getters.

Required Methods

fn get_t<T: OxiExtract>(&self, key: &str) -> Result<T::Out>

Gets a required typed value from the dictionary using the OxiExtract trait.

Fails if the key is absent.

Errors

• The key is missing.
• The value exists but cannot be converted to the requested type (unexpected kind).

fn get_opt_t<T: OxiExtract>(&self, key: &str) -> Result<Option<T::Out>>

Gets an optional typed value from the dictionary using the OxiExtract trait.

Returns Ok(None) if the key is absent instead of treating it as an error.

Errors

• The value exists but cannot be converted to the requested type (unexpected kind).

fn get_dict(&self, keys: &[&str]) -> Result<Option<Dictionary>>

Gets an optional nested Dictionary by traversing a sequence of keys.

Returns Ok(None) if any key in the path is absent.

Errors

• A value is found for an intermediate key but it is not a Dictionary (unexpected kind).

fn get_required_dict(&self, keys: &[&str]) -> Result<Dictionary>

Gets a required nested Dictionary by traversing a sequence of keys.

Fails if any key in the path is missing.

Errors

• A key in the path is missing.
• A value is found for an intermediate key but it is not a Dictionary (unexpected kind).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
