Struct CsvRow

Source

pub struct CsvRow<'a> {
    pub fields: Vec<&'a str>,
    pub headers: Option<&'a [String]>,
}

Expand description

CSV input row. Columns indexed by 0-based position OR by header name (when the InputFormat says has_header = true).

Fields§

§fields: Vec<&'a str>§headers: Option<&'a [String]>

Implementations§

Source §

impl CsvRow<'_>

Source

pub fn get(&self, ident: &str) -> Option<&str>

Look up a column. AWS Select supports both bare column_name (when the CSV has a header) and _1, _2, … positional refs. Returns None if the identifier doesn’t resolve.
