Struct TableDescription 

pub struct TableDescription { /* private fields */ }

An owned duckdb_table_description with indexed column-name/default access.

Implementations

impl TableDescription

pub fn error(&self) -> Option<String>

The description’s error message, if any.

(duckdb_table_description_error.) The returned string is owned by the description and freed on destroy; it is copied out here and never freed.

pub fn column_name(&self, index: u64) -> Option<String>

The name of the column at index, or None if DuckDB returns no name.

index must be within the table’s column count (obtained from a trusted bounds source — see the module docs); the returned name is owned.

pub fn column_has_default(&self, index: u64) -> Result<bool>

Whether the column at index has a DEFAULT expression.

Errors

Returns an error if DuckDB reports failure for index (e.g. out of range).

Trait Implementations

impl Debug for TableDescription

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for TableDescription

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
