Struct DuckStringView 

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

A parsed view of a duckdb_string_t value.

This type borrows from the raw vector data — it does not allocate.

Safety

The data slice from which this view is created must outlive the view. For pointer-format strings, the pointed-to heap data must also be valid.

Implementations

impl<'a> DuckStringView<'a>

pub const fn from_bytes(raw: &'a [u8; 16]) -> Self

Creates a DuckStringView from the raw 16-byte representation.

The input is a fixed-size [u8; 16] reference, so the size is enforced at compile time.

pub const fn len(&self) -> usize

Returns the length of the string in bytes.

pub const fn is_empty(&self) -> bool

Returns true if the string is empty.

pub fn as_str(&self) -> Option<&'a str>

Returns the string as a UTF-8 str slice, or None if it is not valid UTF-8.

The returned &'a str has the same lifetime as the underlying data slice — not the lifetime of self. This allows the result to outlive the DuckStringView.

Safety

For pointer-format strings (length > 12), the pointer stored at bytes 8–15 must be a valid pointer to at least self.length bytes of string data that is live for lifetime 'a.
