Implementations

impl ClearableValue

fn single_till_newline(input: &mut &str) -> ModalResult<Self>

Recognizes a ClearableValue::Single while handling the surroundings.

Cleared values are represented by non-existing values.

Consumes leading and trailing spaces while also consuming newlines. Also allows variables at the end of the file where no newline is found. Calls Value::parse_next_value for variable parsing.

Errors

Returns an error if no ClearableValue::Single is found in input.

fn list_till_newline(input: &mut &str) -> ModalResult<Self>

Recognizes a ClearableValue::Array while handling the surroundings.

Cleared values are represented by the non-existance of a value.

Consumes leading and trailing spaces while also consuming newlines. Also allows variables at the end of the file where no newline is found. Calls Value::parse_next_value for variable parsing.

Errors

Returns an error if no ClearableValue::Array is found in input.
