Struct EventRow 

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

Zero-copy, read-only accessor for a fixed-layout event row.

All field accessors are #[inline] for compiled-code performance. Type correctness is validated with debug_assert (zero overhead in release builds).

Implementations

impl<'a> EventRow<'a>

pub fn new(data: &'a [u8], schema: &'a RowSchema) -> Self

Creates an EventRow from a byte slice and schema.

Panics

Debug-asserts that data.len() >= schema.min_row_size().

pub fn data(&self) -> &'a [u8]

Returns the underlying byte slice.

pub fn schema(&self) -> &'a RowSchema

Returns the schema.

pub fn is_null(&self, field_idx: usize) -> bool

Returns true if the field at field_idx is null.

Null bitmap convention: bit = 1 means null, bit = 0 means valid.

pub fn get_bool(&self, field_idx: usize) -> bool

Reads a bool field.

pub fn get_i8(&self, field_idx: usize) -> i8

Reads an i8 field.

pub fn get_i16(&self, field_idx: usize) -> i16

Reads an i16 field.

pub fn get_i32(&self, field_idx: usize) -> i32

Reads an i32 field.

pub fn get_i64(&self, field_idx: usize) -> i64

Reads an i64 field. Also accepts FieldType::TimestampMicros.

pub fn get_u8(&self, field_idx: usize) -> u8

Reads a u8 field.

pub fn get_u16(&self, field_idx: usize) -> u16

Reads a u16 field.

pub fn get_u32(&self, field_idx: usize) -> u32

Reads a u32 field.

pub fn get_u64(&self, field_idx: usize) -> u64

Reads a u64 field.

pub fn get_f32(&self, field_idx: usize) -> f32

Reads an f32 field.

pub fn get_f64(&self, field_idx: usize) -> f64

Reads an f64 field.

pub fn get_str(&self, field_idx: usize) -> &'a str

Reads a variable-length UTF-8 string field.

pub fn get_bytes(&self, field_idx: usize) -> &'a [u8]

Reads a variable-length binary field.

pub fn field_ptr(&self, field_idx: usize) -> *const u8

Returns a raw pointer to the field’s inline data for JIT code.

pub fn timestamp(&self) -> i64

Convenience: reads field 0 as i64 (convention: field 0 is event time).

Trait Implementations

impl<'a> Debug for EventRow<'a>

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

Formats the value using the given formatter.
