Struct RawOffsetTraceBuilder 

pub struct RawOffsetTraceBuilder<'a, 'b> { /* private fields */ }

Builder for recording expected MMIO accesses at a fixed raw byte offset.

Returned by ExpectedTraceBuilder::at.

Operations on RawOffsetTraceBuilder return &mut Self, allowing read-modify-write sequences at the same offset to be chained:

let mock_builder = MockMmioRegionBuilder::new(0x1000);
mock_builder.expect(|t| {
    t.at(0x08).read32(0x0000_0001).write32(0x0000_0003);
});
let mut mmio = mock_builder.build();
assert_eq!(mmio.load32(0x08), 0x0000_0001);
mmio.store32(0x08, 0x0000_0003);

Implementations

impl<'a, 'b> RawOffsetTraceBuilder<'a, 'b>
