Module buf_redux::strategy [−] [src]

Types which can be used to tune the behavior of BufReader.

Some simple strategies are provided for your convenience. You may prefer to create your own types and implement the traits for them instead.

Structs

AtEndLessThan	A `MoveStrategy` which triggers if there is no more room at the tail at the end of the buffer, and there are fewer valid bytes in the buffer than the provided value.
AtEndLessThan1k	A `MoveStrategy` which tells the buffer to move data if there is no more room at the tail of the buffer, and if there is less than 1 KiB of valid data in the buffer.
FlushAtLeast	Flush the buffer if it contains at least the given number of bytes.
FlushAtLeast8k	Flush the buffer if it contains at least `8Kb (8192b)`.
FlushOn	Flush the buffer if it contains the given byte.
FlushOnNewline	Flush the buffer if it contains a newline (`\n`).
IfEmpty	A `ReadStrategy` which tells the buffer to read more data only when empty.
LessThan	A `ReadStrategy` which returns `true` if there is fewer bytes in the buffer than the provided value.
NeverMove	A `MoveStrategy` which always returns `false`. Use this to restore original `std::io::BufReader` behavior.
WhenFull	Flush the buffer if there is no more headroom. Equivalent to the behavior or `std::io::BufWriter`.

FlushStrategy	A trait which tells `BufWriter` when to flush.
MoveStrategy	Trait for types which `BufReader` can consult to determine when it should move data to the beginning of the buffer.
ReadStrategy	Trait for types which `BufReader` can consult to determine when it should read more data into the buffer.

DefaultFlushStrategy	The default `FlushStrategy` for this crate.
DefaultMoveStrategy	The default `MoveStrategy` for this crate.
DefaultReadStrategy	The default `ReadStrategy` for this crate.
