Implementations§
Source§impl CsvParseOptions
impl CsvParseOptions
Sourcepub fn with_separator(self, separator: u8) -> Self
pub fn with_separator(self, separator: u8) -> Self
The character used to separate fields in the CSV file. This is most often a comma ‘,’.
Sourcepub fn with_quote_char(self, quote_char: Option<u8>) -> Self
pub fn with_quote_char(self, quote_char: Option<u8>) -> Self
Set the character used for field quoting. This is most often double quotes ‘“’. Set this to None to disable quote parsing.
Sourcepub fn with_eol_char(self, eol_char: u8) -> Self
pub fn with_eol_char(self, eol_char: u8) -> Self
Set the character used to indicate an end-of-line (eol).
Sourcepub fn with_encoding(self, encoding: CsvEncoding) -> Self
pub fn with_encoding(self, encoding: CsvEncoding) -> Self
Set the encoding used by the file.
Sourcepub fn with_null_values(self, null_values: Option<NullValues>) -> Self
pub fn with_null_values(self, null_values: Option<NullValues>) -> Self
Set values that will be interpreted as missing/null.
Note: These values are matched before quote-parsing, so if the null values are quoted then those quotes also need to be included here.
Sourcepub fn with_missing_is_null(self, missing_is_null: bool) -> Self
pub fn with_missing_is_null(self, missing_is_null: bool) -> Self
Treat missing fields as null.
Sourcepub fn with_truncate_ragged_lines(self, truncate_ragged_lines: bool) -> Self
pub fn with_truncate_ragged_lines(self, truncate_ragged_lines: bool) -> Self
Truncate lines that are longer than the schema.
Sourcepub fn with_comment_prefix<T: Into<CommentPrefix>>(
self,
comment_prefix: Option<T>,
) -> Self
pub fn with_comment_prefix<T: Into<CommentPrefix>>( self, comment_prefix: Option<T>, ) -> Self
Sets the comment prefix for this instance. Lines starting with this prefix will be ignored.
Sourcepub fn with_try_parse_dates(self, try_parse_dates: bool) -> Self
pub fn with_try_parse_dates(self, try_parse_dates: bool) -> Self
Automatically try to parse dates/datetimes and time. If parsing fails,
columns remain of dtype DataType::String
.
Sourcepub fn with_decimal_comma(self, decimal_comma: bool) -> Self
pub fn with_decimal_comma(self, decimal_comma: bool) -> Self
Parse floats with a comma as decimal separator.
