pub struct ColumnName<'a> { /* private fields */ }

Expand description

A validated column name.

This type simply wraps a &str.

You can use it to construct it explicitly to avoid re-validating the same names over and over.

Implementations

source

impl<'a> ColumnName<'a>

source

pub fn new(name: &'a str) -> Result<Self>

Construct a validated table name.

source

pub fn new_unchecked(name: &'a str) -> Self

Construct an unvalidated column name.

This breaks API encapsulation and is only intended for use when the the string was already previously validated.

Invalid column names will be rejected by the QuestDB server.
