Brr.Blob
Blob objects.
See the Blob Interface.
module Ending_type : sig ... end
The line ending type enum.
val init : ?type':Jstr.t -> ?endings:Ending_type.t -> unit -> init
init ()
is a blob initialisation object with given properties.
The type for Blob
objects.
of_jstr ~init s
is a blob containing the UTF-8 encoded data of s
.
val of_array_buffer : ?init:init -> Tarray.Buffer.t -> t
of_array_buffer ~init b
is a blob containing the bytes of b
.
val byte_length : t -> int
byte_length b
is the byte length of the blob.
type' b
is the MIME type of b
or Jstr.empty
if unknown.
slice ~start ~stop ~type b
are the bytes in range [start
;stop-1
] as blob. start
defaults to 0
and stop
to byte_length b
.
If start
or stop
are negative they are subtracted from byte_length b
. This means that -1
denotes the last byte of the blob.
type'
specifies the resulting type for the blob, defaults to the empty string.
val array_buffer : t -> Tarray.Buffer.t Fut.or_error
array_buffer b
is an array buffer with the contents of b
.
val text : t -> Jstr.t Fut.or_error
text b
is the string that results from UTF-8 decoding the contents of b
.
val data_uri : t -> Jstr.t Fut.or_error
data_uri b
is b
as a data URI (via the FileReader
API).
