Struct ReaderOptions 

pub struct ReaderOptions {
    pub batch_size: usize,
    pub max_record_bytes: usize,
    pub max_batch_bytes: usize,
    pub max_depth: usize,
    pub projection: Option<Vec<usize>>,
}

Batch size, projection, and XML limits.

Fields

batch_size: usize

Maximum rows returned per batch. Default: 1024.

max_record_bytes: usize

Maximum record bytes, including inherited namespaces. Default: 8 MiB. Also caps input events. Records are checked after writing each event; temporary buffers may exceed this limit.

max_batch_bytes: usize

Maximum sum of serialized record bytes per batch. Default: 64 MiB. Must be at least max_record_bytes; excludes Arrow allocations.

max_depth: usize

Maximum element depth (1..65535). Default: 128.

projection: Option<Vec<usize>>

Output columns in order; None selects all, Some(vec![]) only counts rows.

Implementations

impl ReaderOptions

pub fn validate( &self, schema: &XmlSchema, record_path: &str, ) -> ReaderResult<()>
