Struct TokenFilterLoader 

pub struct TokenFilterLoader {}

Implementations

impl TokenFilterLoader

pub fn load_from_value( kind: &str, value: &Value, ) -> LinderaResult<BoxTokenFilter>

pub fn load_from_cli_flag(cli_flag: &str) -> LinderaResult<BoxTokenFilter>

Loads a token filter based on a CLI flag string.

Arguments

• cli_flag - A string slice representing the command-line interface (CLI) flag used to specify the token filter. The flag typically contains both the filter kind and its arguments.

Returns

Returns a LinderaResult<BoxTokenFilter>, which is a boxed token filter, or an error if the CLI flag is invalid or the filter configuration cannot be loaded.

Process

1. Parse CLI flag:
   • The parse_cli_flag function is called to extract the filter kind and its arguments from the cli_flag string.
2. Load filter from parsed values:
   • The filter kind and arguments are passed to load_from_value, which constructs the appropriate token filter based on the parsed values.

Errors

• If the CLI flag cannot be parsed, an error is returned.
• If the filter kind or its configuration is invalid, an error is returned during the filter loading process.

Details

• The CLI flag is parsed into a filter kind and arguments. These are then used to load the appropriate token filter using the load_from_value function.
