Fields

input: PathBuf

Input CSV file to inspect

sample_rows: usize

Number of rows to sample when inferring types (0 means full scan)

delimiter: Option<u8>

CSV delimiter character (supports ‘,’, ‘tab’, ‘;’, ‘|’)

input_encoding: Option<String>

Character encoding of the input file (defaults to utf-8)

mapping: bool

Emit column mapping templates to stdout after probing

overrides: Vec<String>

Override inferred column types using name:type

snapshot: Option<PathBuf>

Capture or validate a snapshot with header/type hash and sampled value summaries (writes if missing)

na_behavior: NaPlaceholderBehavior

How to treat NA-style placeholders (NA, N/A, #N/A, #NA)

na_fill: Option<String>

Replacement value used when –na-behavior=fill (defaults to empty string)

assume_header: Option<bool>

Force header detection outcome (true treats first row as header, false treats it as data)

Trait Implementations

impl Args for SchemaProbeArgs

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 SchemaProbeArgs

fn clone(&self) -> SchemaProbeArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaProbeArgs

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

Formats the value using the given formatter.

impl FromArgMatches for SchemaProbeArgs

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