Struct NntpProxyBuilder 

pub struct NntpProxyBuilder { /* private fields */ }

Builder for constructing an NntpProxy with optional configuration overrides

Examples

Basic usage with defaults:

let config = load_config("config.toml")?;
let proxy = NntpProxyBuilder::new(config)
    .with_routing_mode(RoutingMode::Hybrid)
    .build()?;

With custom buffer pool size:

let config = load_config("config.toml")?;
let proxy = NntpProxyBuilder::new(config)
    .with_routing_mode(RoutingMode::PerCommand)
    .with_buffer_pool_size(512 * 1024)  // 512KB buffers
    .with_buffer_pool_count(64)         // 64 buffers
    .build()?;

Implementations

impl NntpProxyBuilder

pub fn new(config: Config) -> Self

Create a new builder with the given configuration

The routing mode defaults to Standard (1:1) mode.

pub fn with_routing_mode(self, mode: RoutingMode) -> Self

Set the routing mode

Available modes:

• Standard: 1:1 client-to-backend mapping (default)
• PerCommand: Each command routes to a different backend
• Hybrid: Starts in per-command mode, switches to stateful when needed

pub fn with_buffer_pool_size(self, size: usize) -> Self

Override the default buffer pool size (256KB)

This affects the size of each buffer in the pool. Larger buffers can improve throughput for large article transfers but use more memory.

pub fn with_buffer_pool_count(self, count: usize) -> Self

Override the default buffer pool count (32)

This affects how many buffers are pre-allocated. Should roughly match the expected number of concurrent connections.

pub fn build(self) -> Result<NntpProxy>

Build the NntpProxy instance

Errors

Returns an error if:

• No servers are configured
• Connection providers cannot be created
• Buffer size is zero

Trait Implementations

impl Debug for NntpProxyBuilder

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

Formats the value using the given formatter.
