Struct ColumnData 

pub struct ColumnData {
    pub columns: Vec<String>,
}

Multi-column data for aligned tree formatting

Represents a tree node with multiple columns that should be aligned vertically when rendered. Each column is a separate string value.

Examples

use tree_fmt::ColumnData;

// Create node with 3 columns: name, version, path
let data = ColumnData::new( vec![
  "api_ollama".to_string(),
  "v0.1.0".to_string(),
  "(api/ollama)".to_string()
]);

assert_eq!( data.columns.len(), 3 );

Fields

columns: Vec<String>

Column values for this node

Implementations

impl ColumnData

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

Create new column data from vector of strings

Arguments

• columns - Vector of column values

Examples

use tree_fmt::ColumnData;

let data = ColumnData::new( vec![
  "name".to_string(),
  "value".to_string()
]);

pub fn from_pairs(pairs: Vec<(&str, &str)>) -> Self

Create column data from key-value pairs

Only the values are stored, keys are discarded. Useful for self-documenting code when building column data.

Arguments

• pairs - Vector of (key, value) pairs

Examples

use tree_fmt::ColumnData;

let data = ColumnData::from_pairs( vec![
  ( "name", "api_ollama" ),
  ( "version", "v0.1.0" ),
  ( "path", "(api/ollama)" )
]);

assert_eq!( data.columns.len(), 3 );
assert_eq!( data.columns[ 0 ], "api_ollama" );

pub fn len(&self) -> usize

Get number of columns

pub fn is_empty(&self) -> bool

Check if column data is empty
