Fields

delimiter: String

CSV delimiter character. [Default: ‘;’]

exclude_null_cols: bool

Exclude columns containing only null values [requires data file].

force_string_patterns: Option<String>

Regex pattern(s) matching columns to force read as String type [requires FILE_PATH].

null_values: String

Comma-separated values to treat as NULL. [Default: "", <N/D>]

path: PathBuf

Optional path to the data file (CSV, JSON, NDJSON, Parquet).

query: Option<String>

SQL query to apply after loading data [requires data file].

regex: Option<String>

Apply regex to normalize specific string columns containing European-style numbers.

table_name: String

Table name for SQL queries [requires -q/–query]. [Default: AllData]

Implementations

impl Arguments

pub fn build() -> Arguments

Build Arguments struct.

Trait Implementations

impl Args for Arguments

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for Arguments

fn clone(&self) -> Arguments

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for Arguments

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for Arguments

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for Arguments

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for Arguments

fn parse() -> Self

Parse from std::env::args_os(), exit on error.

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,
