Dala.Blob (dala v0.0.2)

Copy Markdown View Source

Binary data handling via blob references.

Blobs are stored temporarily in an ETS table with a reference atom.

Examples

# Create a blob from binary data
blob_ref = Dala.Blob.create(<<1, 2, 3>>, "application/octet-stream")

# Slice a blob
sliced = Dala.Blob.slice(blob_ref, 0, 2)

# Convert to base64
base64 = Dala.Blob.to_base64(blob_ref)

# Save to file
{:ok, path} = Dala.Blob.to_file(blob_ref, "/tmp/blob.bin")
