Struct Reader 

pub struct Reader {
    pub hashes: Vec<InputHash>,
}

Fields

hashes: Vec<InputHash>

Implementations

impl Reader

pub fn each( &mut self, path: &Path, required: &[&str], each: impl FnMut(&Row) -> Result<()>, ) -> Result<()>

Hash path, check its header, and hand each record to each in file order.

pub fn reread( &self, path: &Path, required: &[&str], each: impl FnMut(&Row) -> Result<()>, ) -> Result<()>

A second pass over a file this reader already hashed. The file must be unchanged, and it is not recorded again, so the manifest’s input list is the same as for a single pass.

pub fn table(&mut self, path: &Path, required: &[&str]) -> Result<Vec<Row>>

pub fn table_where( &mut self, path: &Path, required: &[&str], keep: impl Fn(&Row) -> bool, ) -> Result<Vec<Row>>

Like Reader::table, keeping only the rows keep accepts.

pub fn lines(&mut self, path: &Path) -> Result<BTreeSet<String>>

Trait Implementations

impl Default for Reader

fn default() -> Self

Returns the “default value” for a type.
