State
State is a package for managing state.
Cells
Cells are compare-and-swap cells. They support reading and compare-and-swapping the data.
Content-Addressed Data
Content-addressed data stores identify pieces of data by their hash. Posting to the store returns the hash of the data, which can be used later to retrieve the data, and verify that it is correct.
Key-Value Stores
Interfaces for Key-Value and transactional Key-Value stores are defined at state.KVStore and state.KVStoreTx.
POSIXFS
Interfaces and utility functions for dealing with filesystems as defined by POSIX.

func IsErrNotFound ¶
Types ¶
type ByteSpan ¶
ByteSpan represents a lexicographically sorted span of []byte. The span is [Begin, End), meaning Begin is included, and End is excluded. End is ignored if set to nil, and the span is assumed to have no upper bound. When Begin is the empty []byte, it implies no lower bound, since it is inclusive.
type ErrNotFound ¶
type ErrNotFound[K any] struct { Key K }
func (ErrNotFound[K]) Error ¶
func (e ErrNotFound[K]) Error() string
type Span ¶
type Span[T any] struct { // contains filtered or unexported fields }
Span is a specification for iteration through values of type T. It includes begin and end bounds, which can be inclusive or exclusive of the bounding value. The empty Span is equivalent to TotalSpan() and includes all elements of type T.
func (Span[T]) Compare ¶
Compare determines if an element T is below the Span, in the Span or above the Span. The output should be interpretted as s - x. Similar to bytes.Compare and strings.Compare. If the span > x then 1. If the span < x then -1. If the span contains x then 0.
func (Span[T]) IncludesLower ¶
IncludesLower returns true if there is a lower bound and it is inclusive
func (Span[T]) IncludesUpper ¶
IncludesUpper returns true if there is an upper bound and it is inclusive
func (Span[T]) LowerBound ¶
LowerBound returns the Span's lower bound and true if the span has a lower bound.
func (Span[T]) UpperBound ¶
UpperBound returns the Span's upper bound and true if the span has an upper bound.
func (Span[T]) WithLowerExcl ¶
WithLower returns a copy of s with an exclusive lower bound.
func (Span[T]) WithLowerIncl ¶
WithLowerIncl returns a copy of s with an inclusive lower bound
func (Span[T]) WithUpperExcl ¶
WithLowerExcl returns a copy of s with an exclusive lower bound
func (Span[T]) WithUpperIncl ¶
WithUpperIncl returns a copy of s with an inclusive upper bound
func (Span[T]) WithoutLower ¶
WithoutLower returns a copy of s with no lower bound.
func (Span[T]) WithoutUpper ¶
WithoutUpper returns a copy of s with no upper bound.
