Struct CsvTable 

pub struct CsvTable {
    pub headers: Vec<String>,
    pub rows: Vec<Vec<String>>,
}

An in-memory table of string-valued cells.

Columns are named; rows are VecString`. Provides the foundation for type inference, merge/join, pivot, and diff operations.

Fields

headers: Vec<String>

Column headers.

rows: Vec<Vec<String>>

Data rows (each row has headers.len() fields, padded with "" if short).

Implementations

impl CsvTable

pub fn new(headers: Vec<String>) -> Self

Create an empty table with the given headers.

pub fn from_str(data: &str, delimiter: char) -> Result<Self, Error>

Parse a CSV string into a CsvTable using the given delimiter.

pub fn to_csv_string(&self, delimiter: char) -> String

Serialize back to a CSV string with the given delimiter.

pub fn column_index(&self, name: &str) -> Result<usize, Error>

Look up a column index by name.

pub fn column_values(&self, name: &str) -> Result<Vec<&str>, Error>

Get all values from a named column as strings.

pub fn column_f64(&self, name: &str) -> Result<Vec<f64>, Error>

pub fn row_count(&self) -> usize

Number of data rows (excluding header).

pub fn col_count(&self) -> usize

Number of columns.
