Struct VlenStringReadOptions 

pub struct VlenStringReadOptions { /* private fields */ }

Allocation limits for reading variable-length strings.

Limits are checked before any string payload is materialized. The payload byte limit covers the bytes referenced by the VL elements; it excludes the Vec<String> and String allocation metadata.

Implementations

impl VlenStringReadOptions

pub const fn new() -> Self

Create options with no limits.

pub const fn with_max_elements(self, max_elements: usize) -> Self

Set the maximum number of VL elements that may be read.

pub const fn with_max_payload_bytes(self, max_payload_bytes: usize) -> Self

Set the maximum total string payload size in bytes.

pub const fn max_elements(&self) -> Option<usize>

Return the configured element limit.

pub const fn max_payload_bytes(&self) -> Option<usize>

Return the configured payload-byte limit.

Trait Implementations

impl Clone for VlenStringReadOptions

fn clone(&self) -> VlenStringReadOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for VlenStringReadOptions

impl Debug for VlenStringReadOptions

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

Formats the value using the given formatter.

impl Default for VlenStringReadOptions

fn default() -> VlenStringReadOptions

Returns the “default value” for a type.

impl Eq for VlenStringReadOptions

impl PartialEq for VlenStringReadOptions

fn eq(&self, other: &VlenStringReadOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
