Struct Vector 

pub struct Vector { /* private fields */ }

A factory for creating loggers that store messages in an in-memory Vec.

The Vector factory is ideal for unit testing, allowing you to capture logs in a thread-safe list and verify them later. Unlike string-based loggers, this preserves the structured Message data.

Default Configuration

• Capacity: 1024 (Pre-allocated slots for log messages).
• Max Retries: 3 (Attempts to re-send if the buffer is temporarily locked).
• Worker Count: 1 (Ensures sequential insertion order in async mode).

Implementations

impl Vector

pub fn new(capacity: usize, max_retries: usize, worker_count: usize) -> Self

Creates a new Vector factory with explicit settings.

pub fn get_capacity(&self) -> usize

Returns the initial pre-allocated capacity for the message buffer.

pub fn get_max_retries(&self) -> usize

Returns the currently configured maximum retry attempts.

pub fn get_worker_count(&self) -> usize

Returns the currently configured background worker count.

pub fn capacity(self, capacity: usize) -> Self

Sets the initial capacity of the internal vector.

Pre-allocating capacity helps avoid expensive reallocations during high-frequency logging events.

pub fn max_retries(self, max_retries: usize) -> Self

Updates the maximum number of retry attempts for the buffer.

pub fn worker_count(self, worker_count: usize) -> Self

Updates the background worker count.

Note: Using multiple workers with a vector may result in logs being inserted out of chronological order.

pub fn build(self, concurrency: Concurrency) -> Logger

Finalizes the builder and returns a high-level Logger.

pub fn build_impl_direct(self) -> Box<DirectLogger>

Builds the underlying DirectLogger implementation.

pub fn build_impl_queued(self) -> Box<QueuedLogger>

Builds the underlying QueuedLogger implementation.

pub fn build_service(self) -> Box<Vector>

Internal helper to construct the service::Vector instance.

Trait Implementations

impl Default for Vector

fn default() -> Self

Provides sensible defaults for in-memory message capturing.

• capacity: 1024
• max_retries: 3
• worker_count: 1
