Implementations§

Source§

impl SeekerBuilder

Source

pub fn new() -> Self

Create a new SeekerBuilder with default configuration.

Source

pub fn with_capacity(capacity: usize) -> Self

Create a new SeekerBuilder with provided capacity.

Source

pub fn delimiter(&mut self, delimiter: u8) -> &mut Self

Set the delimiter to be used by the created Seeker.

This delimiter must be a single byte.

Will default to a comma.

Source

pub fn quote(&mut self, quote: u8) -> &mut Self

Set the quote char to be used by the created Seeker.

This char must be a single byte.

Will default to a double quote.

Source

pub fn buffer_capacity(&mut self, capacity: usize) -> &mut Self

Set the capacity of the created Seeker’s buffered reader.

Source

pub fn sample_size(&mut self, size: u64) -> &mut Self

Set the sample size of the seeker, i.e. the maximum number of records the seeker will attempt to prebuffer to collect some useful statistics about target CSV stream.

Will default to 128.

Source

pub fn lookahead_factor(&mut self, factor: u64) -> &mut Self

Set the lookahead factor of the seeker, i.e. an approximate number of records the seeker will read ahead when calling Seeker::find_record_after.

Will default to 32.

Source

pub fn has_headers(&mut self, yes: bool) -> &mut Self

Indicate whether first record must be understood as a header.

Will default to true.

Source

pub fn from_reader<R: Read + Seek>( &self, reader: R, ) -> Result<Option<Seeker<R>>>

Create a new Seeker using the provided reader implementing std::io::Read.
